Integrated wind power generator

Abstract

An integrated wind power generator is a device that integrates the functions of a wind turbine and a generator. In the main part of the induced structural component are located the induction circuits, the core and the coil, and in the motor-inducer component, the blades supports and the induction poles are placed. When wind circulation occurs, the energy acting on the blades causes the motor-inducer component to rotate around the induced structural component generating a rotating magnetic field inducing an EMF in the induction circuits. Electricity is generated in the induction circuits through only one device, functionally inseparable, in which both motor and generator functions are integrated.

Description

BACKGROUND OF THE INVENTION [0001] (1) Field of the Invention [0002] This invention consists of an integrated wind power generator that in only one device integrates the functions of a turbine and a generator. [0003] (2) Prior Art [0004] Machines that convert wind kinetic energy into electrical energy are called “Wind Generators” or “Aero-generators”. This type of machine is subdivided into two groups: low-power Aero-generators and high-power Aero-generators or Power Aero-generators. The former are low performance units whose power ranges from some hundreds of watts (w) to some tens of kilowatts (Kw). In general, they are light, low-complexity machines, used to feed small consumption units located far from the grid. The latter are machines with enough power to connect to the grids that feed important consumption centers. The power of these machines ranges from some hundreds of Kw to several megawatts (Mw), and their technological complexity is far different from the former. In the e...

Benefits of technology

[0011] This invention consists of an integrated mechanism that in only one device integrates the turbine and the generator. This concept reduces many of the moving components of the equipment, since it does not require the use of a speed increaser or of individual rotating components.

[0012] Technologies and innovations applied to the design of this equipment also allow size reduction in contrast to the traditional multi-pole turbine-generator assemblies, due to the special design in the arrangement of generator active components and, in some arrangements, of the use of permanent magnets, also eliminating the rotating devices of energy transmission for inductor excitation. Consequently, this device allows minimizing important disadvantages caused by multi-pole generators with direct connection, such as size and weight, and at the same time, offers its main advantage represented by the absence of a speed increaser.

[0014] As mentioned before, as auxiliary devices that increase speed are avoided, the device requires less maintenance work (as a reference, it is relevant to point out that this device rotates fewer times in twenty years of operation than a high-speed generator does in three months). Likewise, the particular design of the different components' arrangement decreases the loads in the tower structure, which reduces efforts and prolongs main roller bearing lifetime and tower active components.

[0015] Finally, this invention consists of a Power Aero-generator with significant advantages regarding efficiency, availability, reliability, operating costs and maintenance.
